Some tests for the to_search_value method of the various field types. #3
Few fixes:

* Fix an issue where the presedence of  and  was getting mixed up and so the default value was being returned when it should have been the none value
* Fix not passing kwargs through to super.__init__ from TextField
* The logic flow in TextField's to_search_value now makes more sense
* Return none_value in all cases where it should be returned
* Get rid of IntegerField inheriting from FloatField and causing a none_value rounding error
* Fix the typechecking in DateField.to_search_value so that it checks for datetimes first (since  is a subclass of Sun 19 Aug 2012 23:29:28 BST)
* Fix using FORMAT instead of self.FORMAT in DateField methods
